If this error occurs confirm that the windows firewall is not turned on when reviewing the Raiser's Edge web server and Raiser's Edge database server.  If the windows firewall is turned on disable it and review the testconfiguration page again.

Note:  Refreshing IIS may be required after updating the windows firewall settings on both servers.

Please contact the appropriate software vendor or IT professional for assistance with this process or issue which is beyond Blackbaud's scope of support.
